COMBINED LETTER-SHEET ANT) ENVELOP.

Specification of Letters Patent.

Application filed May 21, 1909.

Patented May 3, 191i). Serial No. 497,527.

To all whom it may concern:

Be it known that I, EDWARD MAREN-Co- I won, a citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented new and useful Improvements in Combined Letter- Sheets and Envelops, of which the following is a specification.

This invention relates to a combined letter sheet and envelop.

The object of this invention is to provide an article of this character which may be stamped from a single blank of material, the front, rear walls and end flaps of said walls being adapted to originally occupy a common plane with respect to each otherwhereby a letter may be written upon one side of the blank, after which the flaps and front and rear walls may be folded to form an envelop adapted for the usual transmlssion through the mail.

A still further object of my invention is to construct the front and rear walls and their flaps in such manner that when folded a pocket will be provided upon the interior of the envelop which may be used as a container for articles or matter to be mailed.

Other objects and advantages will be apparent as the nature of the invention is better set forth, and it will be understood that changes within the scope of the claims may be resorted to without departing from the spirit of the invention.

In the drawing, forming a portion of this specification and in which like numerals of reference indicate similar parts in the sev' eral views :Figure 1 is a rear view of the envelop. Fig. 2 is a plan view of the blank from which the envelop is formed. Fig. 3 is a section taken on the line 33 of Fig. 1.

In the drawing, the envelop is shown as being formed from a single blank of sheet material particularly illustrated in Fig. 2. The blank consists of a front wall 1, a rear wall 2 adapted to normally occupy a common plane with respect to each other, and as illustrated the rear wall has integrally formed therewith at its ends flaps 3 which also occupy a common plane with the walls 1 and 2. The front wall 1 is provided at its ends with flaps 4 similar to the flaps 3. The blank from which the envelop is formed is scored upon the line 5 which terminates at its ends at points between the lower ends of the flaps 3 and the upper ends of the flaps 4 as shown in Fig. 2. The blank is also scored upon the lines 6 which extend transversely to the line 5 and these lines extend throughout the transverse area of the said blank as clearly shown. This construction is such that the flaps 3 and 1 may be folded to lie in parallel relation to the front and rear walls, whereupon, the blank can be folded upon the line 5 at points between the ends of the front and rear walls. The rear wall 2 is preferably provided with a longitudinal extension 6 in which is formed an elongated longitudinally extending slot 7. The front wall 1 has formed integrally therewith at its upper end a sealing tongue 8 which is gummed upon one side as shown at 9 and is adapted to be moistened and secured to the outer surface of the rear wall as clearly illustrated in Fig. 1. The sealing tongue is provided at its center with an outwardly extending neck 10 which carries an auxiliary tongue 11. The tongue 11 is preferably of heart or arrow form and is partly gummed upon one side as shown at 12 and gummed in a similar manner upon its other side as shown at 13.

Having briefly described the manner in which the blank can be folded it will be seen that by moistening the gummed port-ions of the auxiliary tongue, the said tongue may be inserted in the slot 7 formed in the exten sion 6, whereupon, the gummed portion 12 can be engaged with one of the flaps 3, and the gummed portion 13 engaged in a similar manner with one of the flaps 4. It will of course be understood that upon moistening the gummed portions 12 and 13 of the auxiliary tongue the gummed portion 9 of the sealing tongue 8 will be correspondingly moistened so that the said sealing tongue can be engaged with the rear wall of the envelop approximately simultaneously with the attachment of the gummed portions of the auxiliary tongue with the end flaps 3 and 4. After the envelop has been folded it will be seen that pockets l4: and 15 are provided between the front and rear walls, the said pockets being separated by the flaps 3 and 4.. This construction permits the pockets to be used as containers for articles or matter to be transmitted with the envelop. When it is desired to open the envelop, the tongue 8 can be separated from the front wall 1 by cutting the said tongue upon the longitudinal line 16, after which it will be readily apparent that the flaps 3 and 4: and the front and rear walls are free from each other and may be unfolded whereby the said front and rear walls and end flaps respectively lie approximately in a common plane with each other. It will be readily appreciated that matter may be retained upon the inner faces of the front and rear walls and their end flaps, and upon folding the envelop as hereinbefore described such written matter will be concealed.

I claim 1. A combined letter sheet and envelop comprising a front and a rear wall having flaps formed integrally therewith at their ends, said flaps being adapted to be folded to lie in a plane parallel with the said front and rear walls, a sealing tongue carried by the front wall adapted to be engaged with the rear wall and an auxiliary tongue carried by the sealing tongue, said auxiliary tongue having a gumlned portion upon each side, one of said gumnied portions being adapted to be engaged with one of the flaps of the front wall and the other gunnned portion being adapted to be engaged with one of the flaps of the rear wall.

2. A combined letter sheet and envelop comprising a front and a rear Wall adapted to normally occupy a common plane with each other, end flaps carried by the front wall and disposed normally in a common plane therewith, end flaps carried by the rear wall and normally disposed in a C0111- mon plane therewith, said front wall and said rear wall being adapted to be folded to lie in parallel'relation to each other, said end flaps being adapted to be folded to lie in juxtaposition with each other and in a plane parallel with the said front wall and the said rearwall respectively,said rear wall having a slot formed therein, a sealing tongue carried by the front wall, said sealing tongue having a gummed portion adapted to be secured to the rear wall and an auxiliary tongue carried by the sealing tongue, said auxiliary tongue having a gummed portion upon each side, said tongue being adapted to be inserted in the slot formed in the rear wall whereby one of its gummed portions can be engaged with one of the end flaps of the rear wall and the gummed portion engaged with one of the end flaps of the front wall. I

In testimony whereof I atfix my signature in presence of two witnesses.
